Derek Smith

A Word of Thanks to our Lake Steward, Derek Smith

For the past ten years, Derek Smith has made significant contributions to the water quality program on Otty Lake. Working with our former Lake Steward Murray Hunt, Derek supported the testing program, helped interpret our water quality data, and did site visits around the lake to investigate algae or aquatic vegetation reported by residents. And for the past four years Derek has served as Lake Steward himself, bringing his considerable experience and expertise to managing all elements of our water testing and monitoring program, including answering residents' questions about our lake. We have all benefited significantly from his diligence and commitment to Otty Lake.

This is Derek's last year as Lake Steward on Otty Lake when he'll be handing the job over to Kevin Terrion who will work with a small group of volunteers to continue the water quality work.

Thank you Derek for the years of dedication to Otty Lake, and we hope to be able to continue benefiting from your expertise as a kowledgeable lake resident for years to come.

bear at feederBlack Bears around Otty Lake

Bears Bears are frequently seen in the Otty Lake watershed, and can peacefully coexist with residents.   Educate yourself on their behaviour in case you encounter one.  Bears are attracted to food of any kind, so be careful how you deal with garbage, fruit trees, barbeques and bird feeders. Generally, bears want to avoid humans. Most encounters are not aggressive and attacks are rare.

Emergency: Call 911.

If people, pets or livestock are in immediate danger.

Non Emergency: Call 1-866-514-2327
